15.5 Unsupported Languages

In addition to the other fully-supported programming languages,
gdb also provides a pseudo-language, called minimal.
It does not represent a real programming language, but provides a set
of capabilities close to what the C or assembly languages provide.
This should allow most simple operations to be performed while debugging
an application that uses a language currently not supported by gdb.

If the language is set to auto, gdb will automatically
select this language if the current frame corresponds to an unsupported
language.
